The reactants of two chemical equations are listed. Equation 1: CuSO4 and NaOH Equation 2: Fe and CuSO4 Based on the type of reaction, which reaction can be used to extract copper metal from copper sulfate solution? (5 points) Select one: a. Equation 2, because Fe being more reactive, replaces Cu from CuSO4 b. Equation 2, because Fe being more reactive, replaces S from CuSO4 c. Equation 1, because Na being more reactive, exchanges position with Cu in CuSO4 d. Equation 1, because Na being more reactive, exchanges position with S in CuSO4

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
